.l'ipplication filed February 13, 1920. Serial No. 358,506.

To allwfio m, it rim z/ concern.

Be it known that T, Bar H. MANsoN, a citizen ot'the United States, residing at Rochester, in the county Monroe and tate of New York, have invented certain new and useful Improvements in Clamps,

ot which the tollowing is a full, clear, con- 'ment through the spring action of a clamp.

. For a more detailed description of the invention, reference is made to the drawings wherein Fig. 1 represents a side elevation partially in section of a dial impulse sender seemed to a desk telephone stand by means of the clamp or the present invention. This section is taken on the line 1-1 of Fig. 2.

Fig. 2 is bottom view of the desk stand with the bottom plate removed to show the with the bottom plate removed to show the arrangement ot' the clamp and impulse sender. Fig. 8 is a plan view of the clamp.

in the drawings Sdesignates a telephone instrument herein illustrated as a desk stand which maybe oitany well known design, although, it will he understood that-the present invention can he used with a so called wall telephone set in which the casing is provided with an opening to receive the dial sender. Tt has not been deemed necessary to illustrate how the present in,- vention would he used with a wall telephone set as last 'mentioned. since this use will be obvious to anyone skilled in the art.

The desk stand 5 is provided with an annular raised portion 19 having an opening patented September 17, 1918, and is provided with a base 20, having extensions 7 Two of these extensions are provided with 'lugs 8, while a third is provided with a set screw 9. These lugs 8 and the set screw 9 are engaged by a clamp generally designated 1.0 and shown in Fig. 3. The clamp 10 is substantially annular in form and is provided with arms .11, which serve as handles when the clamp is being adjusted. The clamp 10 is also provided with notches 12, so positioned that the lugs 8 and the set screw 9 will pass through,

and an additional cut-out portion 13 is necessa'ry so that the lower portion 01 the finger stop 15, with ts holding screw 22, will enter therein when the clamp is being adjusted.

The annular portion of the clamp is provided with cam sections 16, made resilient toadapt tor lnequalities in the position of the lugs and with an embossed portion 18 which tends to give greater resiliency to certain portions of the clamp.

lVhen it is desired to secure the impulse senderv 6 to the telephone instrument 5, the bottom plate (not shown) of the telephone is removed and the impulse transmitter is placed in the opening of the telephone instrument from the upper side, as shown in y big. 1 with the finger stop 15 engaging the notch 21 to prevent rotation of the impulse sender. The clamp is then inserted in the lower side of the desk stand as illustrated in this figure, .so that the periphery of the clamp engages the inner surfaces of the an 'anular raised portion 19, to insure that the impulse sender. 6 is properly centered. The arms 11 .are then moved in a clockwise direction, so that the lugs 8 engage the 1nclined portion of? the cam sections 16 as "accidental movement of the clamp with respect to the impulse sender.

I The screw 2 of the stop '15 limits the clockwise more me'nt ot the cam. The embossed portion 18 serves as one of the bearings for the clamping member 10 against the flat surface. of the raised portion 19 of the telephone instrument, and. also tends to give greater resiliency to the annular portion. of the clamp extending between the two cam sections 16.

In the present arrangement the telephone instrument has been shown with a raised portion 19, with which the clamp 10 00- operates to center the impulse sender, and

the notrh :31 has been cut in this raised portion with whiehthe stop (to-operates to prevent rotation of the impulse sender. It-

sitioned that they receive the extensions 7* of the impulse sender to properly center and prevent the rotation of thesame.

10 hat I claim is strulnent' having an opening therein, of an impulse sender insertable into said opening, and a spring clamping mechanisn'i for securing said ii npulse sender tosaid telephone instrument.

2/ The combination with a telephone-instrument having an opening therein, of an impulse sender insertableinto said opening from one side-oi said instrument, and spring clamping mechanism adjusted from the opposit-e side of said instrument to secure said imp'ulsese'nder to said telephone instrument.

3. The combination with a telephone instrumenthaving an opening, of an impulse sender insertable into saidopening from one side of said instrument, and clamping mechanism having a resilient portion for securing said impulse sender to said telephone instrument.

[4; The combination with a-telephone instrume-nt having an opening, of an impulse sender-having extensions insertable into said opening from one side of said instrument, and. clamping. mechanism having resilient cam surfaces engaging said. extensions, and portions to engage said telephone instrument whereby said impulse sender may be secured to said telephone instrument.

5. The combination with a telephone instrument having anopening therein, of an impulse sender insertable into said opening from one side of said telephone instrument, and an annular member adjusted from the opposite side of said telephone instrument for securing said sender to said telephone instrument. 1 GnThe combination with a telephone instrument having an opening therein, of an impulse sender insertable into said opening from one side of said telephone instrument, and an annular member provided with resilient portions to engage said. impulse sender and with portions to engage said telephone instrument. a

:7. The combination with a telpehone instrument having an opening therein, of an impulse sender insertable into said opening from one side of said telephone instrument,

.1. The combination with at elephone ininstrument.

8. 'lheeombination with atelep'hone instrument having" an" lopening- 1 therein, of a impulse sender provided with extensions insertable into said opening, lugs on said extensions,andan"annular clamping member provided with cut-out portions to receive said extensions, cam surfaces on said annular masher toengage saidlugs, and portions on'said annular member to'engage said telephone instrument.

The combination with a telephone instrumenthaving an opening therein, of an impulse sender insertable into said opening from one side of said instrument, means for centering said impulse sender with respect to said telephone instrument, and spring clampingmechanism for s'ecuring'said impulse sender to said telephone instrument.

10. The combination witha telephone in strument having an opening therein, of an impulse sender insertable into said opening from one side of said instrument, means for centering and for preventingthe movement of said impulse sender, and springclamping mechanism for securing said impulse sender to said telephone instrument.

'11. The combination witha'telephone instrument having an opening therein, of an impulse sender having extensions insertable into said opening, and a cam member engaging said extensions and said telephone instrument to secure said impulse sender to said telephone instrument.

12, The combination-with a telephone instruinent provided with a raised portion and an opening therein, of an impulsesender provided with extensions insertable into said opening, and a clamping member engaging said raised portion and said extensions for centering and securing said impulse sender on said telephone instrument.

r 13. The combination with atelephone instrument havingasupport, of an impulse transmitter provided with lugs and cams for engaging said lugs to secure said impulse transmitter to said support.

14. The combination with a telephone instrument having a support, of an impulse transmitter provided with lugs and resilient cams for engaging said lugs to secure said impulse transmitter to said support.
